[TYPO3-calendar] import .ics typo3 6.2

[Dirk Steffens]

Hello,

with the actual version of cal (1.6.0) it seems not possible to import any .ics-file.
I was researching the whole sunday.
I've tried it with several files, but system generates only categories but no event item.

Has anybody running the combination cal(1.6.0), typo3 (6.2), import .ics-file?

Thanks for reading and any answer.

Regards 
Dirk
